No. 33,220 3 Claims. (Cl. 297-32) This invention relates to a collapsible rocking chair.

Chairs of this general type embody a rocker base frame, an upper frame collapsible relative to the base frame, struts extending between the upper and base frames and a collapsible seat mounted on the upper frame and struts. It is the aim of the present invention to provide an improved structure in such a device.

In a rocking chair according to the invention, the frame is pivotally mounted to the rocker base frame near one end and connected to the rocker base frame near the other end by collapsible struts. A seat structure including a back part and a seat part is pivoted to the upper frame and struts, so that when the chair is collapsed, the back part is folded over the seat part.

The invention will subsequently be described in more detail particularly with reference to the drawings in which:

FIGURE 1 is a perspective view of the rocking chair of the invention in set-up condition.

FIGURE 2 is a longitudinal cross-section along the line 22 of FIGURE 1.

FIGURE 3 is a perspective view of the rocking chair of the invention partially collapsed.

FIGURE 4 is a longitudinal cross-section along the line 44 of FIGURE 3.

FIGURE 5 is a perspective view of the rocking chair of the invention fully collapsed.

Referring more particularly to the drawings, the chair is made up of a base frame A of metal tubing of substantially rectangular formation. This frame is made up of curved side bars 15 and 17 meeting the respective end bars 19 and 21.

A substantially rectangular upper frame B of metal tubing has curved side bars 25 and 27 which are pivoted as at 26 and 2,8 to the bars 15 and 17 near one end of the frame A. The frame B is completed by a cross bar 29 extending between the side bars 25 and 27. A pair of collapsible struts respectively made up of parts 31, 25 and 33, 100 at each side of the chair, connect the frames A and B at a point remote from 26 and 28, near the opposite end of the base frame A.

The strut part 100 is pivoted at 35 to the bar 27 and the part 33 as at 37 to the bar 17. The part 33 is pivoted to the part 100 as at 39. These two parts are locked in extended position as will be described. Likewise, the part 25 is pivoted to the bar 15 as at 47 and the part 31 to the bar 25 as at 45. The parts 25, 31 and 33, 100 are held in extended position by a spring catch.

A seat structure, indicated generally by C, is mounted on the upper frame B and struts 31, 33. To this end, the seat is provided with a back portion 51 which is pivoted to the bars 25 and 27 at 53 and 55 respectively. The seat '0 has a seat part 57 which is pivoted to the back 51 as at 59 and 61, and to the struts 31 and 3.3 as at 63 and 65 respectively.

Operation In operation, the struts 31 and 33 are extended as shown in FIGURE 1, this retains the frame B in a position spaced from the frame A. When the struts 31 and 33 are collapsed, the frame B may be folded down against the frame A progressively as shown in FIGURES 3 and 5. The seat C will also fold, with the part 51 against the part 57, when the chair is collapsed.

In the preferred form shown, the chair is made of metal tubing, but other materials and forms can be. used.

When the rocking chair is made of metal tubing, the struts 25 and 35 are locked in extended position by the following construction which is best shown in FIGURE 2. The end of the bottom part of the strut 33 is flattened and deformed, as shown, to provide it with a channel portion 33a which when the strut 33, is extended embraces the end of the part 100. A spring 65 on the pivot 39 urges the endof the tube 33 against the end of the tube 100 and resists pivotal movement between these members. However, sufiicient force will overcome the spring and allow the members to be pivotally broken as shown in FIGURES 3 and 5.

The pivot 65 also serves to carry the front end of the the base frame, a back pivoted to the upper frame midway of its height, and a seat pivoted to the bottom of the back and to the struts whereby the seat can move from set-up position when the respective frames are in set-up position to collapsed position when the frames are in collapsed position, and releasable means on the struts for retaining them in extended position and releasing them for collapse.

2. A collapsible rocking chair, comprising, a substantially rectangular rocker base frame, a substantially rectangular upper frame having a pair of parallel arms, each pivoted to the rectangular frame adjacent one end thereof, a pair of collapsible struts extending between the base and upper frames towards the other end thereof, the struts in extended position retaining the second end of the upper frame spaced from the base frame and in collapsed position permitting the upper frame to be folded against the base frame, a back pivoted to the upper frame midway of its height, and a seat pivoted to the bottom of the back and to the struts whereby the seat can move from.

and upper frames toward the other end thereof, the struts in extended position retaining the second end of the upper frame spaced from the base frame and in collapsed position permitting the upper frame to be folded against the base frame, a back pivoted to the upper frame midway of its height, and a seat pivoted to the bottom of the back and to the struts whereby the seat can move from set-up position when the respective frames are in set-up position to collapsed position when the frames are in collapsed position, said struts each being made up of a pair of tubular members each pivoted at one end to the rocker base frame and upper frame respectively and pivoted together at the other end, one of said tubular members being provided with a concave part adapted to fit the tubular end of the other member when the chair is in set-up position, and spring means normally drawing said concave part against said tubular end of the other member 307,556 Ladewig Nov. 4, 1884 thereby to retain the said members in alignment. 1,683,327 Bouharoun Sept. 4, 1928 2,017,599 Lehner Oct. 15, 1935 References Cited in the file of this patent 2,340,790 Aylor Feb. 1, 1944 Y 5 2,727,753 Johnson et a1.
